Power amps: continuous output power measurements

[Sam Ash]

It depends on cooling and music material.
You will have a ton of reserve, any way.

So far I haven't manage to clip them (they have indicators for just about anything) and they drive woofers from 30-250Hz at a 80 m² room.

That's good to know, so do you think 500w to 600w continuous at 4 ohms all- channels driven is about right with the module being cooled?

This chart I found on this thread is confusing. The 4 ohm ratings are lower than the 8 ohm ratings with all channels driven.

Download the whole chart I posted at the previous post, is very detailed.
What you see at this one is continuous vs burst, 8 Ohm is burst - 4 Ohm is continuous.

There's tons of info at the pdf.

I would go with the official info, they are generally honest and say that for continuous expect 2 x 300w with 600W peaks (Amir gives 686W) for both channels driven at 4 Ohm.

Referred to the PDF file as per your recommendation. Here the figures quoted are much higher, is it because these figures don't reflect continuous state ?

These are the specs that I thought reflected the module's continuous power.

This part kind of like mentions continuous and coincides with the ratings you mentioned: 2 x 300w with 600w peaks for both channels driven at 4 ohms.

To be honest I was going by the previous specifications and thought otherwise.

Yes, the continuous power is stated as such.
The rest of them even state the time that can maybe be sustained (60 sec, 90 sec, etc)

Generally is the same lately will all class D amps, you get either the 1/4 or the 1/8 of the stated burst power power as continuous.
With music program is what's needed probably, peaks don't last long. But it's nice to have the reserve not to clip them.

Thank you for the explanation and clarification, it helped me to gain a better understanding in terms of the realistic specifications of the module.

Yes, it's nice that the module has been designed to handle the dynamics aspect.
